Well. Haven't we been a busy boy! 14 hours last weekend polishing the car (I think I may be moving from semi-anal to anal...I'm ashamed to admit that there was a toothbrush involved... what's happening to me :o!), and then around 6 hours being an auto-electrician this weekend!
After some debate & thought, I decided to try one of the 'cheaper' HID kits - I got one that the guys on the FTO forums have been using without problems so far (I think this may be the one Zentac has got..?). £99 inc delivery. We'll see what happens eh.
Nice thing about the kit is it came with an optional separate wiring harness - complete with a 40Amp relay and 20Amp fuse. So you have a choice of doing things the usual way - connecting the old light hallogen harness directly to the ballasts to power them, or to use the separate power harness, in which case all the std hallogen harness does is trigger the HID relay. Power is then supplied on a separate circuit.
I suspect that a lot of the problems with flickery HIDs, failure to ignite etc are related to power problems. Gumpf on my kit said that operating current is 3.5Amps (equivalent to running a 40-50W hallogen bulb), but startup current is around 10Amps - equivalent to running a 120W halogen bulb (by power=voltage x current). I'm not sure what the Skyline's light wiring harnesses are rated at, but 2 x 10 amp startups sounded like a bit much. Besides, I planned to do a dual headlight conversion as well - the skyline uses a separate light unit for mains and dips. When you switch to mains, the dips switch off - not really what you want when you have HID dip beams. Using the separate harness meant I could use a feed from the high beams to trigger the HID relay and keep them burning.
Some pics:

I fitted all the extra bits in relay/fusebox - two new relays - one for HIDs and one for dual beam - 2nd row from the top, along with two inline fuseholders. I drilled an extra hole in the side of the fusebox and put a dirty great grommet in it:

Some before and after pics: I've deliberately not edited the pics at all, so they're straight from the camera to show the real difference:
Halogen dips (80W bulbs):

HID dips (raining, surprise surprise :thinking: ):

Parked the car at the top of the drive for illumination pre and post pics:

I'll have to see how other road users react, but the level of the dip beam does seem a bit high to me. May need a bit of tweaking...
Now. Do I spend another 100 quid and convert the mains to HID too...:yum:
